Abstract [en]

This report will examine various solar energy technologies in order to decide if they could be applied in the Royal Seaport. The Royal Seaport is a Swedish urban district under development in Stockholm, with the goal of becoming a sustainable district. Two main techniques, solar collectors and solar cells, including sub-categories, are addressed in this report. Another sub-category, a hybrid system, will also be mentioned. The main difference between solar collectors and solar cells is the type of energy produced by the system. Solar collectors generate heat, while solar cells generate electricity.Analysis of the different systems shows that solar collectors can supply the entire domestic hot water need, during the summer, in the Royal Seaport. While the electricity from the solar cells is negligible in comparison to the buildings electricity need, even during summertime. Nevertheless, the solar cells could provide electricity to the electric vehicles that will be used in the area. A solution that is suitable for the royal Seaport would be to cover 25% of the roof area by flat plate collectors and solar cells integrated into the rest of the roof surface, i.e. 75%. With this solution, the Royal Seaport of Stockholm will achieve its objectives in the best possible way.
